Question(Author, Title, Pages) Example: The Bus Ride Taking the Dory Jagna Transit costs P 15.00 for the first ten kilometers $(10 \mathrm{~km})$. Each additional ten kilometers adds $P 5.00$ to the fare. Moreover, if the trip reaches forty kilometers, the additional rate becomes $P 10.00$ for each ten-kilometer additional distance. Note that the vehicle's route is from Jagna to Tagbilaran (vice versa) only.
How much will a passenger pay for: a) a 5-kilometer ride? b) a 30-kilometer ride? c) a 60-kilometer ride?
Solution: a) For a 5-km ride: Since $P 15.00$ is the minimum fare, then for a minimum distance of 10 km , therefore a passenger will pay $P 15.00$. b) For a $30-\mathrm{km}$ ride: Since 30 km is beyond the minimum distance, and since the additional rate becomes $P 5.00$ per ten kilometers, we then have,
Fare $=$ minimum fare + additional fare We must solve for the "additional fare" first: $$\begin{array}{l} \text { Additional Fare }=\text { additional rate } \times(\text { distance travelled }- \text { min. } \text { distance }) \\ \text { Additional Fare }=\left(\frac{\mathbf{P} 5.00}{10 \mathrm{~km} / \mathrm{h}}\right) \times(30-10) \mathrm{km}=\mathrm{P} 10.00 \end{array}$$
Therefore, we get, $$\text { Fare }=\mathbf{P} 15+\mathbf{P} 10=\mathbf{P} \underline{25.00}$$ Exercises: 1) Solve for item c in the example. (Hint: Solve first for the "new minimum fare" at the distance of 40 km , which is now the "new minimum distance" to be considered.) 2) If you are the passenger en route to Tagbilaran City (roughly 69.79 km . away from Jagna), how much will you pay for the fare? (Note: Think practical.)
